TLDR
The confinement of light within a hollow core (a large air hole) in a silica-air photonic crystal fiber is demonstrated and certain wavelength bands are confined and guided down the fiber.Abstract:
The confinement of light within a hollow core (a large air hole) in a silica-air photonic crystal fiber is demonstrated Only certain wavelength bands are confined and guided down the fiber, each band corresponding to the presence of a full two-dimensional band gap in the photonic crystal cladding Single-mode vacuum waveguides have a multitude of potential applications from ultrahigh-power transmission to the guiding of cold atomsread more

Nitrous oxide detection at 5.26 µm with a compound glass antiresonant hollow-core optical fiber.
TL;DR: A borosilicate antiresonant hollow-core fiber is used for laser-based gas sensing due to its unique structure and guidance, which provides low-loss, single-mode transmission and the feasibility of using the fiber as a gas cell was verified.
